Specification of Letters Patent.

Patented Feb. 4, 1913.

To all whom it may concern:

Be it known that I, Orro PROCHNOW, a citizen of the United States,residing at lVest'Allis, county of Milwaukee, and State of Wisconsin,have invented new and useful Improvements in Strap-Supports for Guns, ofwhich the following is a specification.

My invention relates to improvements in strap supports for guns. 0

The object of my invention is to provide means which .will facilitatethe use of a strap in supporting a gun from the shoulder of the user,and in which the strap will be automatically taken care of when not inuse.

In the drawingsFigure 1 is a side view of the gun embodying myinventiomFig. 2 is a detail sectional view of the spring housing drawn to a planetransverse to the Winding shaft and showing the spring in positiontherein. Fig. 3 is a sectional view of the spring and strap housings,drawn to a plane which includes the axis of the shaft and the openingthrough which the strap projects, the strap and sprin being illustratedin full within the houslngs with the projecting end of the strappartially broken away. Fig. 4 is a detail sectional View of the straphousing, drawn to a plane transverse to the winding shaft and showingthe strap therein partially wound upon such shaft.

Like parts are identified by the same reference characters throughoutthe several views.

The stock of the gun A is provided with a cylindrical cavity near itslower margin, adapted to receive a cylindrical housing B containing awinding spring C. A similar housing D of greater axial diameter isadapted to contain a strap E. The two housings B and D may be regardedas constituting one member sub-divided by a partition F to form a springreceiving cavity 1) and a strap receiving cavity d.

A transverse shaft G constitutes the winding shaft, the inner end of thespring being secured to this shaft, as illustrated at H in Fig. 2. Theouter end of the spring is doubled u on itself to form a hook I, whichextends t rough an opening in the casing. The hook I may also extendinto the material composing the stock A of the n to assist in lookingthe casing in position in .the stock. The strap E is wound upon theshaft G within the cavity (2, the inner end of the strap being securedto the shaft at g. The strap extends through an opening J in the casingD and its outer end is provided with a snap hook K adapted to engage aneye bracket L attached to the barrel of the gun at any convenient point.

In use, the stra is drawn out against the tension of the wlnding springC and the ,snap hook K engaged with the eye bracket L. The spring 0tends to wind up the strap, thereby holding it at tension in theposition' in which it is illustrated in full lines in Fig. 1, exceptwhen the strap is being used to support the gun. When used to supportthe gun, the strap may be drawn out from the casing and looped over theshoulder of the user, the strap being shown by dotted lines in Fig. 1,when partially drawn out for such purpose. When the gun is removed fromthe shoulder of the user, the spring automatically winds up the strap toits tension position, as illustrated in Fig. 1. If desired, the snapbook may be disengaged from the bracket L, whereupon the entire strapwill be drawn into the cavity 03, where it will be completely hiddenexcept as to the snap hook K, which is too large to enter the apertureJ. Where a wooden stock is employed, the socket which receives thecasings B and D is preferably so formed that the wood will partiallycover the sides of the casing, as shown at M in Fig. 1, at

one or bot-h sides of the stock. A covering strip N of wood may beapplied and secured in position after the casing has been inserted inthe cylindrical cavity provided therefor. constitutes a retaining memberto prevent the casing from slipping out laterally.

I claim- 1. The combination with a gun provided with a cavity in thestock thereof, a casing mounted in said cavity and provided with awinding shaft, a winding spring operatively connected to said shaft, anda gun supporting strap operatively connected to said shaft at one sideof the winding spring, said casing having an aperture through which saidstrap may extend and said strap being provided with means for connectingits outer end to the barrel of a gun on the under side, the strap beingadapted to A wooden strip N in such case wholly enter said casing and tobe wound upon said shaft in a coil parallel to the winding spring.

2. The combination with a gun stock provided with a transversecylindrical cavity, a casing in said cavity subdivided by a partitioninto a plurality of housings, a shaft extendin through the partition,and traversing sai housings, a spring wound upon said shaft in one ofsaid housings, with its inner end secured thereto and its outer endconnected with the housing and connecting the housing and stock, and astrap wound upon said shaft in the other housing and provided with aprojecting member adapted to be connected with the gun barrel, saidcasing being slotted to permit the strap to extend through it,substantially as described.

In testimony whereof I afiix my signature in the presence of twowitnesses.

OTTO PROCHNOW.
